The stone quarry

In the Roman era there was a quarry for a green stone called bardiglio. It was used extensively in the construction of Augusta Praetoria: for building facings, road paving, plaques, stele, blocks, and tombstones.

The existence of a village where workers lived may be assumed, along with a road that connected the area with the new city and that continued toward the bridge of Pont-d'Ael, whatever its function.

Now the quarry is no longer used, but following the path that leads from Montbel toward Turlin, a careful observer can still recognize signs of it.
